3.Lateral and posterior leg lift exercises (inward, outward and posterior leg lift in the healthy side, affected side lying and prone position).
4.Weight-bearing and balance exercises: stand on both feet, shoulder-width apart; or stand apart in front and behind. Move the center of gravity, so that the feet alternate weight-bearing, and gradually transition to the affected leg standing on one foot, 5 minutes / time, 2-3 times / day.
5, flexion exercises (1 week to start): flexion of the knee to 60 degrees, immediately after the exercise ice 15-20 minutes, once a day, no repeated exercises.
II. Mid-term (3-6 weeks) 1. Quadriceps isometric training.
2, Each lateral and posterior leg lift changed to resistance.
